Suppose your the proud owner of a super powerful computer, and you really like to play World of Warcraft, would you like to see the devs develop an HD texture pack so that you could enjoy nicer graphics? Doesn't have to be anything major as in art redesign - this isn't about make the game look more realistic, it's about making it more detailed. So...if the devs could, would you show your support for that? Also, this wouldn't be forced upon anyone, it'd be an optional download.
Note: Textures would bring the game's textures to 2k resolution. Would affect all content.
